Royal Purple 20-500 Extended Life Premium Engine Oil Filter

Royal Purple focuses exclusively on developing state-of-the-art lubricants to outperform other oil brands. That includes best-in-class fuel system cleaners, synthetic gear oil, oil filters, and more to help you get peak performance out of your engine. Make your car, boat, motorcycle, snowmobile, or other motorized gear more reliable, and protect their longevity with the best lubricants, engine fluids, and oil filters. Your oil filter is the last line of defense before contaminants get into the heart of your vehicle. Those contaminants can lower your engine’s performance and cause costly damage. All moving parts in an engine need clean oil to function. A premium filter maintains the quality of the oil circulating in the lubrication system, keeping your engine running efficiently for a lot longer. Royal Purple Extended Life Engine Oil Filters with silicone anti-drain back valves use 100% synthetic micro-glass filtration media supported by steel mesh backing for superior particle removal. The quality of an oil filter is stated as a percentage of particles caught at a certain size or larger. Royal Purple boasts 99% filtration efficiency at 25 microns or larger, and 80% at 10 microns. We don’t believe in messing with perfection, so we only produce one type of oil filter with variations for different motor vehicles. Not all engine oil filters have an anti-drain back valve, but all Royal Purple Extended Life Automotive Spin-On Oil Filters do. The purpose of an anti-drain back valve is to avoid dry starts that can really grind on your engine. Anti-drain back valves prevent oil drain back when you shut off the vehicle, leaving just enough behind for startup. Our valve is built to last, constructed from durable silicone that outlasts standard rubber in both extreme hot and cold temperatures. The shell of our filter is heavier for extra strength and security from road debris puncture. Heavy-duty nitrile rubber base gasket and metal end caps provide a positive seal and prevent leaks. Changing your oil yourself shouldn’t take very long and can save you some money. The question we get most often is, “When do oil filters need to be changed?” If your car is still under , follow the manufacturer’s recommended change interval. If not, the filter and the oil go hand in hand. When the oil goes, the filter goes. Dirty or clogged oil filters can allow contaminants to pass through or block the flow of oil to your engine. It's not recommended to change our oil filter without changing the oil. You can install your oil filter using the instructions on the filter, using a filter wrench as needed. Royal Purple is compatible with all synthetic and conventional oils.
From the manufacturer

Royal Purple Extended Life Oil Filter
Royal Purple manufactures only one type of oil filter – the super-premium Extended Life Oil Filter, designed and engineered to match superior particle removal with optimized flow for maximum engine protection and filter life. Built smarter and stronger, Royal Purple synthetic oil filters continuously outperform in the toughest conditions.
Superior Filtration
The 100% synthetic micro-glass media we use to make Extended Life filters provides superior particle removal – with 99% filtration efficiency at as small as 25 microns.

Design and Construction Advantages
Each Royal Purple oil filter features thicker shell material for extra strength and extra security against puncture from road debris. Metal end caps provide each oil filter with a positive seal for filter element assembly. The center tube is designed to prevent filter element collapse.
A 100% screen-backed synthetic media provides superior filtration while keeping flow restriction low. The by-pass valve is engineered to ensure oil flow in situations of excessive filter element flow restriction. A heavy-gauge steel backplate provides each filter with higher burst strength. The gasket made of premium nitrile rubber with special lubricity compound reduces torque during installation and removal.
Finally, the silicone anti-drain back valve prevents dry starts by eliminating oil drain-back during shutdown. The anti-drain back valve is made of silicone, which outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures.
Conventional Filter
Magnified 250 times, a microscope shows large spaces in conventional cellulose filtration fibers. The spaces allow larger particles to enter the oil stream and infiltrate the engine.
Royal Purple Filter
Royal Purple's filter media uses the latest technology filtration system to catch particles as small as 25 microns.
